Résumé:
In this contribution we present a new database of experimental values of K-shell fluorescence yields published during the period 1994-2014, for elements with atomic numbers 14 ≤ Z ≤ 82. We present also the results of the empirical calculation of K-shell fluorescence yields using the fit of the experimental values. Finally we presented our results with other theoretical and semi-empirical values published by other authors.
